Seventh year in and I am at the sours stage - thinking it is worth the time commitment. I make a lot of lagers in 10 gallon AG batches for the crew still, but I want to explore the more exotic styles 5 gallons at a time...or even smaller perhaps. There is so much out there to try, I only wish I had started sooner in life. But I thank the friend who started me on this path every time I see him!
